Here is a proposed release schedule for 23.0, the next major release of Bitcoin Core. I've aimed for a release 7 months after the (-final) release of the last (#20851), 7 instead of 6 months (as is customaryl) to not have a crunch time so soon after the new year.

2022-02-02 ✔️

• Open Transifex translations for 23.0
• Soft translation string freeze (no large or unnecessary string changes until release)
• Finalize and close translations for 0.21

2022-02-15 ✔️

• Feature freeze (bug fixes only until release)
• Translation string freeze (no more source language changes until release)

2022-03-01 ✔️

• Split off 23.x branch from master
• Start RC cycle, tag and release 23.0rc1
• Start merging for 24.x on master branch

2022-04-01 ✔️

• Release 23.0 (actual release date 2022-04-26)

If any specific dates or timeframes are a problem for you, let me know.
